Making use of [1, Lemma 2.1], Hölder’s integral inequality, and other analytic techniques, some inequalities of Hermite-Hadamard type were established. However, there are some vital errors appeared in main results of the paper [1].

The aim of this paper is to correct these errors and we now start off to correct them.

Correction to Theorem3.1. Let be a differentiable function on such that for . If is s-geometrically convex and monotonically decreasing on for and , then
where

Proof. Since is s-geometrically convex and monotonically decreasing on , using Lemma 2.1 and Hölder’s inequality gives
Let and . Then
When , we have
When , by (7), we obtain
When , by (7), we have
Substituting (8) to (13) into (6) yields inequality (1).Since is s-geometrically convex and monotonically decreasing on , by Lemma 2.1 and Hölder’s inequality, we obtain
When , we have
When , by (7), we obtain
When , by (7), we have
Substituting (15) to (20) into (14) leads to inequality (2). Theorem 3.1 is thus proved.

Correction to Corollary 3.2. Under the conditions of Theorem 3.1,(1)when ,
(2)when ,

Correction to Theorem3.3. Let be a differentiable function on such that for . If is s-geometrically convex and monotonically decreasing on for and , then
where is the same as in (4),

Proof. Since is s-geometrically convex and monotonically decreasing on , by Lemma 2.1 and Hölder’s inequality, we have
When , we have
When , by (7), we obtain
When , by (7), we have
Substituting (28) to (33) into (26) and (27) results in inequalities (23) and (24). Theorem 3.3 is thus proved.

Correction to Corollary3.4. Under the conditions of Theorem 3.3, when , we have

Correction to Theorem4.1. Let , , and . Then
where
for and with are the arithmetic, logarithmic, and generalized logarithmic means, respectively.

If , then

Proof. Let , , and for . Then the function is s-geometrically convex on for ,
and . Therefore,
By Theorem 3.1, Theorem 4.1 is thus proved.

Correction to Theorem4.2. Let , , and . Then

Proof. It is easy to see that
Hence, by Theorem 3.3, Theorem 4.2 is thus proved.

Remark. By the way, all the powers which appeared four times in [2, Theorem 4.2 and Corollary 4.2] should be corrected as , respectively.
